Is OneThread Sales Email Generator Free?

Yes. As of January 2026, the tool is 100% free to use with no hidden paywalls, trial periods, or mandatory signups. It’s offered as a lead magnet by OneThread but functions independently of their paid CRM platform.

Alternatives

• HubSpot’s AI Email Writer: Requires a HubSpot account; limited free tier.
